Hardware conditioning in process of high speed imaging

The accuracy of slow motion cinematic analysis depends on frame rate of used camera. Specific case of cinematic analysis is in medical research focusing on microscopic objects (cilia of respiratory epithelium). Higher frame rate of camera (400 fps e.g.) causes that exposure time for camera sensor is too short, so it is necessary to use lightning source with higher optical (illuminating) efficiency and higher reliability. Hardware conditions are also limited by used light microscope. Paper focuses on design of LED illumination modules, their control, modes and supplying circuits for high speed imaging purposes.
